Yul Brown's favorite demonstration is TO DRIVE BY CAR 1600 KM WITHOUT FUEL only a can with 4 liters of water and two Brown batteries that convert water into gas. Brown gas is obtained by electrolysis of water, in which hydrogen and oxygen are separated. This is nothing new or complicated - electrolysis was discovered nearly two centuries ago by Faraday. The new thing is that when the two gases then mix, even under pressure, they do not explode, but connect peacefully and quietly. „From water and again to water with clean energy that can purify water, air, food, the world in general.“ So Brown formulated his own discovery.

This article proposes an approach for short-term forecasting of electricity production from a micro grid connected PV system using the means of artificial intelligence. An artificial neural network is used to create the model. The forecasting model has three input variables: solar radiation, wind speed and air temperature, and one output variable - the amount of electricity produced by the installed photovoltaic panels in the microsystem. This study is a part of a project for optimization of the energy consumption of a building in case that independent alternative renewable energy sources are used. The model is implemented and tested on real data collected in 5 minutes from a specially designed meteorological station installed in the building of the Burgas Free University.

Inverter welding sources are replacing conventional sources due to their convincing advantages - small size and weight, easy ignition and high quality of the arc, high energy and economic performance, operation in all conditions. The rapid development and implementation of transistor welding inverters became possible after the development of suitable power transistors (JGBT). Multi-station welding sources have more power than conventional welding sources. This places higher demands on their energy performance, which requires very precise design and selection of the element base. The purpose of this article is to study the energy performance of a multi-station inverter- welding source associated with switching losses at different welding currents.

Welding current regulators are used in multi-station welding units, which are used in robotic welding complexes, for example when welding stator packages of electric motors, or large gas pipes in which it is simultaneously welded with 2-4 burners. The rapid development and implementation of inverter welding sources became possible after the development of suitable power transistors (JGBTs) and transistor modules. Multi-station welding sources have more power than conventional welding sources. This places higher demands on their energy performance, which requires very precise design and selection of the element base. The purpose of this article is to study the energy performance of transistor welding current regulators to obtain good energy performance.

In this paper, it is aimed to determine the possible existence of the volatility spillover effect between the seven cryptocurrencies (Bitcoin, Ethereum, Tether, BNB, Ripple, Cardano and Dogecoin) from which the largest sample volume can be obtained among the top ten cryptocurrencies with the dollar index and the highest market value. intended. For this purpose, using daily data between 31 December 2017 and 09 February 2023, the possible existence of the spillover effect between the dollar index and cryptocurrencies in return and volatility was investigated with the causality test in the mean and variance developed by Hong (2001). According to the results obtained from the causality test on average, a one-way causality relationship has been determined from the Dollar index to Bitcoin, Ethereum, BNB, Ripple and Cardano. This result shows that the changes seen in the prices of Bitcoin, Ethereum, BNB, Ripple and Cardano cryptocurrencies in the returns are affected by the price movements seen in the Dollar index. On the other hand, no causal relationship was found between the Dollar index and Tether and Dogecoin. According to the causality test results in variance, it has been determined that there is a bidirectional volatility spillover effect between the Dollar index and all cryptocurrencies in the study. This result means that Bitcoin, Ethereum, Tether, BNB, Ripple, Cardano and Dogecoin cryptocurrencies will react instantly and their volatility will increase in the face of a new news about the Dollar index; Similarly, if there is a new news on the market about the cryptocurrencies included in the study, the Dollar index will react immediately and its volatility will increase.

The aim of this study is to reveal the financial risk connectedness and risk transmission mechanism between the stock market and the crypto asset market. Thus, it is aimed to contribute to the literature examining the relationships between the crypto asset market and conventional financial markets with new empirical findings and to reveal essential results for investors and policymakers. According to the findings of the research, although the spread from the VIX index to the cryptocurrencies is stronger, the spread from the cryptocurrencies to the VIX index turned out to be quite weak. In the network structure analyzed in the study, there has been a high degree of spread from the stock market and other cryptocurrencies toward ETH and BCH. BTC -clearly dominant-, and the equity market is the net transmitter, while ETH, BCH, LTC, and XRP are net receivers. According to the connectedness index result, the spread from the stock market to the crypto-asset markets is higher than the spread from the crypto-asset market to the stock market. In other words, while the volatility in the stock market is transferred to the crypto asset markets at a certain rate, the volatility observed in the crypto asset market is transferred to the stock market at a less significant level. It can be said that the main risk source for the crypto asset market is BTC. Among the five cryptocurrencies examined, BTC is a net transmitter, and the other four cryptocurrencies are net receivers. In addition, it has been understood that the spillover effect observed in the crypto asset market is largely due to its own internal shocks.

Gastronomy is discussed in terms of multivariate concepts such as food, cuisine, taste, culture, food and beverage products and eating. The concept of gastronomy, which has attracted more attention in recent years and has been dealt with together with tourism, has a scope far beyond just travel and eating and drinking activities. Contrary to popular belief, gastronomic tourism should not only mean traveling to eat or participating in eating and drinking activities during travel, but should be considered as a much broader concept. Individuals can use gastronomic variables (such as experience, taste, curiosity, locality and feature search) as a motivation tool, or the gastronomic elements of a destination can be considered as an attractive force in their travels. Within the scope of gastronomic tourism, different tourism activities can be seen. In this study, the concepts of gastronomy, gastronomy and tourism were mentioned and gastronomic experience was evaluated in tourism. In addition, in this study, some of the tours for gastronomy tourism in Turkey and some of the important destinations in gastronomy tourism in Turkey were discussed. In the study, it was tried to develop suggestions for gastronomy tourism, destinations and other stakeholders by evaluating the secondary sources in the literature.
